Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pet tow rope cushioning tool.

[0002]

2. Description of the Related Art A pet as used herein is generally a dog, but any animal can be used as long as it is an animal that is guided by a tug rope.

[0003] A tug rope is a rope locked to a dog collar or the like, and a person pulls the other end by hand. The material and thickness depend on the animal to be pulled, but normally it is made of nylon and is 5 mm.
Most of them are about 10 mm thick.

It is said that, especially in the case of dogs, if they are kept connected to a rope, stress will build up, which will be bad for the health of the dogs themselves and will be ferocious. Therefore, I usually take a walk about once a day. In this case, even if it is rare to bite another person, a tug rope will be used because it may surprise a child or an elderly person or cause a conflict with another dog. Also, depending on the type of dog, the use of tug ropes is obligatory by law or regulation.

[0005]

When the dog walks at the same speed and in the same direction as the human, there is no problem. However, dogs always change direction or start running instantly in response to other dogs or roadside objects. In such a case, if the impact is large, even an adult may fall down, which is extremely dangerous. In addition, the danger is great even when taking a walk on a bicycle. Of course, human beings are more powerful (dogs stronger than themselves cannot walk in principle), so they can be pulled without a momentary impact,
There is no fall.

Further, if such an instant impact occurs frequently and every day, the wrist is considerably burdened and the wrist is hurt.

[0007]

[Means for Solving the Problems] In view of such a current situation,
The present inventor has completed the shock absorbing device of the present invention as a result of earnest research, and is characterized in that it has a shock absorbing elastic body and has locking devices on both sides.

Here, the shock absorbing elastic body is generally a spring. However, rubber or other elastic body may be used. The strength (elastic constant) of this elastic body varies depending on the animal, of course, but normally in a dog that a human walks,
Speaking of being shocked, about 10 to 50 kg in weight
It is of a degree. Therefore, when the dog pulls, it hardly stretches at all times, and when a shock is applied, it is 10 to 50 mm.
A strength and a length that extend to some extent are preferable. Weight 10K
Since there is a considerable difference in impact between the dog of g and the dog of 50 kg, it is natural that the strength of the spring also differs.

When a spring is used as the elastic body, it is preferable to provide a cylindrical container for accommodating the spring, rather than simply providing the spring with locks on both sides. With this configuration, the object is not pinched between the springs. The cylindrical container may be made of metal or plastic. Further, springs having different strengths (spring constants) may be used so as to contract in two stages. It may be simply connected in series, but a spring with a small diameter may be provided inside the one with a large diameter.

Further, since it cannot be said that there is no risk of disengagement when connecting only with elastic bodies such as springs, it is necessary to connect with a wire at the center and adjust the length when the springs extend most. You can also Since the cutting strength of the wire itself is very large and the wire can be firmly attached, the above-mentioned risk of disconnection can be completely avoided.

The locking device may be of any type, and is generally provided at the base of the towline of the dog. It is easy to insert a ring by providing an opening / closing part such as a hook, but when removing the ring, it is better to open the opening / closing part inside. The material is generally metal, but plastic or the like may be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a cross-sectional view showing an example of the cushioning tool 1 of the present invention. A spring 3 is housed inside a cylindrical container 2 in the center, and locking tools 4 are attached to both sides of the spring 3. Impacts from both sides are absorbed by the extension of this spring. This is the basic structure of the present invention.

FIG. 2 is a sectional view showing another example of the present invention. Unlike the example of FIG. 1, this is a type that absorbs a shock by compressing an internal spring. The left hook 5 is the outer cylinder 6
The right hook 7 is fixed to the inner cylinder 8. A spring 9 is fitted between the inner cylinder 8 and the outer cylinder 6.
Further, in order to reduce the metallic sound when sliding, the touch member 10 made of plastic (here, hard polyamide) is used.
Are inserted into both ends of the spring 9.

FIG. 3 is a sectional view of the example of FIG. 2 pulled from both ends. The outer cylinder 6 slides leftward together with the left foots 5, and the inner cylinder 8 slides relatively rightward together with the right hook 7 accordingly. The spring 9 is compressed by the tip bending portion 11 of the outer cylinder 6 and the tip bending portion 12 of the inner cylinder 8. Thereby, the tensile impact is absorbed and relaxed. Further, since the touch portion 10 is slightly larger than the tip bent portion, there is almost no contact between metals, and there is almost no metallic sound when sliding.

FIG. 4 is a sectional view showing still another example of the present invention. This is to pull the internal spring to absorb the shock. The outer cylinder 6 is fixed to the right hook 7, and the inner cylinder 8 is fixed to the left hook 5. And spring 9
Are screwed and fixed by screws 13 which are fixed at their ends. When the hook is pulled to the left and right, the distance between the two screws 13 fixed to the hook increases and the spring 9 extends. At this time, the outer cylinder and the inner cylinder slide. At this time,
A wire 14 is provided at the center to prevent the spring from coming off from the screw and from breaking. this is,
The maximum length of the spring is a taut length, usually slack inside.

FIG. 5 shows still another example of the present invention. This is a type that can absorb two levels. Left hook 5
The inner cylinder is fixed to the right hook 7, and the core cylinder 15 is fixed to the right hook 7. The outer cylinder 6 is free from the left and right hooks. Further, the spring is an external screw 16 between the outer cylinder 6 and the inner cylinder 8.
And two inner screws 17 between the core cylinder 15 and the inner cylinder 8. Here, the spring strength of the inner screw 17 is weaker.

When the hook is pulled left and right, the state shown in FIG. 6 is obtained. The right hook 7 slides to the right, and the inner spring 17 is pressed and contracts accordingly. This is because the bent portion at the tip of the core tube 15 presses the inner spring 17 to the right, and the right end of the inner spring 17 is fixed by the slide fixing tool 18. It is the strength of the outer spring 16 that prevents the slide fixture 18 from moving to the right. Since the outer spring 16 is stronger than the inner spring 17, it functions as a fixture.

Next, when the right hook 7 is further moved to the right side, the inner spring 17 is pressed and cannot be compressed any more, the resistance is naturally stronger than the outer spring, so that the slide fixing member 18 is moved to the right side. . At that time, the outer spring 16 is compressed. This state is shown in FIG. In this way, shock can be absorbed in two stages.

In the example shown in FIG. 5, when the inner spring is made stronger than the outer spring, FIGS. 6 and 7 are reversed, that is, the outer spring is compressed first and then the inner spring is compressed. .

[0020]

As described above in detail, in the shock absorbing device of the present invention, the momentary shock is absorbed by the elastic body, so that the shock to the human hand is remarkably reduced. As a result, it is possible to prevent the wrist from being damaged and reduce the shock to the animal itself. That is, when a dog or the like is connected, the dog itself suddenly jumps out due to the sudden appearance of a car or another dog, and the dog itself receives a considerable impact on the neck or the like.
These can also be reduced.

Further, since the momentary impact is softened, the possibility that the rope or the rope, which is the main body of the tug rope, will be severely reduced.

In the case where the sliding member is made of a plastic member, there is no contact noise between the metals, so that there is no discomfort. Also, with two springs with different strength,
Shock can be absorbed in two stages. This is very effective when a dog or the like tries to run faster than a human being, and the tug rope is always in a tensioned state, and when there is further impact from that state.
